Andreas,
You definitely got the size right and have given us a very fine shot. The lighting and colors are fine with nice detail. I think that the sharpness and DOF could be better if you had used a higher f-stop (around f/11-13) this would create a much great DOF and put more of the shot in sharp focus.

Nice shot! Heavy skies in the background and nice drawings in the packed ice. I'm slightly wondering where you actually focussed on. I feel it has been the big high hump of ice to the left. I agree with Asa, a higher focus depth would have resulted in more sharpness - lower shutter speed as well, but that doesn't matter since nothing is really moving here ;-). Nice one!

Hi there
That is an amazing shot you were able to take. It must have been an incredible trip.
I love all the blues in your photo.
I like the comment on the size.. I am learning that part as well. ;)
